STUMP-PULLER.

Application filed June 30,

To all w zom it may concern Be it known that I, lVAYNn IV. BissnLL, a citizen of the United States, and resident of Rochester, in the county of Olmsted and State of Minnesota, have invented a new and useful Improvement in Stump-Fullers, of which the following is a full, clear, and exact description.

My invention relates to devices for pulling stumps, and it consists in the combinations, constructions and arrangements hereinvdescribed and claimed.

An object of my'invention is to provide a device for pulling stumps on an extensive scale, and to this end the apparatus is so arranged as to permit the pulling of a plurality of stumps at onetime.

A further object of my invention is to provide an arrangement by means of which the stumps are pulled from opposite directions,

so that the stumps on one side of the device afford an anchorage for pulling the stumps on the other side of the device.

' A further object of my invention is to provide a stump pulling device. which is in the nature of a tractor having an engine for operating the same, with a plurality of drums for drawing in the cables by means of which the stumps'are pulled, each of the drums being controlled independently.

'A further object o'f my invention is to provide a stump pulling device having auxiliary drums by means of vwhich the cables of the stump pulling drums may be run'out from the drums to the point at which' the stumps are located.

A further object of my invention is to provide a device of the type described in which the stump pulling capacity is greatly augmented, due to the fact that it hasa greater radius of'operation over that of the ordinary stump puller which has tobe anchored and which pulls in one vdirection only.

Other objects and advantages will appear in the following specication, and the novel features of the invention will be particularly pointed out inthe appended claims.

y invention is illustrated in the accompanying drawings, forming part of `this application, in which- Figure 1 is aside view of the device,

Fig. 2 is a plan view,

Fig. 3 is a front view, A

Fig. 4 is a sectional view substantially on the line 4-4 of Fig. 2,

Fig. 5 is a detailed view of the friction head,

Fig. 6 is a diagrammatic view showing the manner in which the stump pulling cable is run out by the auxiliary drums, and

Fig. 7 is a diagrammatic view showing the manner in, which the stumps are pulled in clusters on opposite sides.

In carrying out my invention, I provide a tractor mechanism of any approved type, such as that of the so-called I-Iolt caterpillar type. The tractor feature forms no part of the invention, except in so far as it coperates with the stump pulling mechanism to produce the result desired.

In the drawings I have shown a fra-me 1 nected with a cross head 7, which is in turn connected by a pitman 3 with a wheel 9`on a crank shaft 10. On the opposite side of the boiler the engine 3 is connected by similar parts numbered 6 to 9 inclusive with a shaft 10 bearing a gear 11 in mesh with a drive gear 12 on a shaftv 13. The latter has a sprocket wheel 14 which is connected by a chain 15 with a sprocket wheel 16 on the shaft 17 (see Figs. 2 and 4). A companion shaft 17 bears va sprocket wheel 16 which is driven by the engine 4. Clutches 18 and 18 on the shafts 17 and 17are provided for throwing into action sprocket wheels 19 and 19 respectively. Sprocket chains 2O and 20 drive sprocket wheels 21 and 21 respectively on a drive shaft 22 for operating the tractor mechanism.

Referring now to Fig. 2, it will be seen that I have provided a gear 23 on the shaft 17, in'mesh with a bevel gear 24 on a shaft 25, mounted in bearings 26 on the frame 27. The shaft 25 bears a gear 28 in mesh with a gear 29 secured to a drum'30 which is rotatably mounted on bearings31. The shaft 25 is provided with a coupling 32 (see Fig. 4) by means of which the gear-28, which is loosely mounted on the shaft, may be brought into operation. A similar coupling 33 brings into operation a gear 34 which engages a large gear 35 on the shaft of an auxiliary drum 36 rotatably mounted in the bearings 31. On the opposite side of the device is mechanism which includes the elements 23 to 36 inclusive which are identical with the elements 23 to 36 inclusive, just described. y It will be noted that the drums are disposed on axes which are parallel with the longitudinal axis ot the vehicle.

Referring now to Figs. 3 and 5, it will be seen that the shaft 13 upon which the sprocket wheels 14 and 14 are mounted has a friction clutch mechanism by means of which the gears 12 and 12 may be operatively connected so as to drive the sprockets. This mechanism consists oit a friction head having a female` member 37 which is arranged to be frictionally engaged by a male member 38, the latter Vbeing secured to the gear 12 and being operated by toggles 39 which are actuated bya movable sleeve 40 when the handle 41 is turned. Power may thus be transmitted through the sprockets 14 and 14' and through the chains 15 and 15 at will, since the opposite end of the device has a similar friction clutch mechanism.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Let us assume that the stump pulling device is at .the position marked A in Fig. 6, and that the stumps have been pulled Yfrom an area on each side thereof, and it is now desired to pull the stumps in the area C. A light cable 42 is carried out `around the snatch `blocks or pulleys 43, 44 and 45 by means of i a horse or in any other suitable manner, and

then back to one of the drums, such as drum 30. VThe end of the-small cable 42 is fastened to theend of the cable 46 on the drum 30, and the auxiliary drum 36 is set into motion to wind up its cable 42, thereby drawing out on the heaviercable 46 to the area C, where the stumps are to be pulled.

`then'secured by branch cables or chains to the various stumps in the area. The cable 46 on the 'opposite side is drawn out in the same manner and attached to the stumps on the `opposite side of thevdevice. The auxillary drums 36 and'36 Vare now disengaged by throwing out the clutches 33V and 33', and

'the `drums 30 and 30` are set in motionby throwing in `the clutches 32 and 32f The `stumps arethus pulled from opposite directions, the stumps on one side of the machine serving `as an anchorage for pulling the stumps on the other side of the machine. This obviates the necessity of anchoring the #stump pulling device itself. Where stumps are pulled on a large scale, it willV be obvious that thisis a great saving of time as well as of labor. The pulling of stumps from opposite sides of the machine also vastly increases the eiiciency of the machine, because it doubles its area of operation. 1t is at times desirable to cut oit the power from one side or the other, and in this respect the machine has all of the necessary adjustments. By means of the handles 41 and 41', either of the gears 12 or 12 may be put into or out ci commission through the operation of the friction clutches, such as that shown in Fig. 5, and as above stated, either side of the traction driving device may be connected or disconnected by means of the clutches 18 or 18', while the clutches controlling the various drums can be manipulated so as to bring any drum into or out of use.

I claim:
